The technology of support for the laneway with big cross section and compound roof condition
At present, there is no a fixed support method for the laneway with big cross section in com plex geology and compound roof condition. So in practice we have to increase cost in order to security. In this paper though analyzing the advantage of the coupling support technique which used rock bolt, beam, net and anchor wire, Account the length of rock bolt and anchor wire though the formula from experience. Fix on the space between each anchor wire according to the pendency theory. Though validate the parame ter of matching between every support method. After all, the author account and fix on the parameter of the coupling support design which under the complex geology condition and compound roof condition.
coupling support which used rock bolt beam net and anchor wire rational parameter of the support
